etcd_docker 7: move etcd dependency down to 3.5.4 (#4151)
Browse files Browse the repository at this point in the history 
This changes our etcd version *down* to 3.5.4 from 3.6.0-alpha.0. In #4087, we made the choice to go to
an alpha version of etcd in order to get around the thorny dependency issues described in that ticket. This was partially on the assumption that
etcd would release a full 3.6.0 version in the months following. As of 9/2/2022, that hasn't happened--no progress seems to have been made on etcd
3.6.0.

As described in #4144, we've since addressed the dependency issues via other means, removing our dependency on the
`embed` and `integration` packages. This allows us to move back to an etcd stable version, 3.5.4. Since stable versions are generally preferable,
I'm taking the opportunity to do so.

// etcd is currently on an alpha version to accomodate a GRPC version upgrade. See
// https://github.com/m3db/m3/issues/4090 for the followup task to move back to a stable version.
// Gory details (why we're doing this):
// Quick note about this etcd version: this version is compatible with our GRPC version (>= 1.41.x) if and only if
// the etcd/embed and etcd/testing/v3/frameworks/integration packages are *not* used. See
// https://github.com/m3db/m3/issues/4144 for a description of the problem.
// As of this writing, we have replaced all usages of those packages with a docker based solution, which eliminates
// the issue. However, if you're seeing conflicts with GRPC and/or otel packages coming from etcd, you may have
// pulled in one of the packages by mistake.
// Use github.com/m3db/m3/src/integration/resources/docker/dockerexternal/etcdintegration
// instead for tests. Don't depend on the `embed` package at all.
//
// Gory details (why the issues occur):
//
// - We import etcd/server/v3 via etcd/embed and etcd/testing/v3/frameworks/integration.
// - etcd/server/v3 in 3.5.2 depends on pre 1.0 opentelemetry. Bleeding edge etcd depends on 1.0 opentelemetry
// - M3 depends on 1.0 opentelemetry — this conflicts with etcd 3.5.2, but not bleeding edge etcd

// Later versions of etcd (>= 3.5.5, >= 3.6.0-alpha.0) have fixed the dependency conflicts, but it is still
// probably better to only depend on the client packages here.
